arm64: defconfig: Enable modules for arm displays

Key devices that support displays on SoCs like the Komeda DRM driver, the
older HDLCD were not enabled by default and should be so displays can work
out of the box on defconfig. Also Candence I2C support should be enabled so
the PHY and thus displays can work too.
